The Japanese Love Yaki Imo
I personally prefer fried sweet potato, but it’s amazing the popularity of Yaki Imo, despite being something so simple and easy to make. It resembles the sale of boiled corn in Brazil.
In Japan, of the 810,000 tons of sweet potatoes produced in 2015, about 60,000 tons were consumed as Yaki Imo.
Besides the sweetness and aroma, the great popularity of roasted sweet potatoes is due to their very low price. There is even a saying that 10 months of work allows you to buy sweet potatoes for the rest of your life.
It was around the 17th century that roasted sweet potatoes began to gain popularity in Japan, first in Ryukyu, then in Honshu, soon roasted sweet potatoes were sold in the suburbs of Kyoto.
Unfortunately, this type of food has lost its massive popularity in recent decades after industrialization and the emergence of other tasty and cheap foods.
